OGG file not working.

[Azerath]

I put in a song to Blockland and it gives me this error:  Stereo sound detected on "4one-Surrealism.ogg" - Removing datablock.

Why?

Is there any way I can fix it so I can play my song?

It must be mono.

How do I change it?

Use an audio editor, and change it to mono.
